Household food waste is a matter of increasing concern for policy makers and organisations because recent research has shown that consumers contribute to about half of the edible food wasted in the developed world. The most applied measure to address the problem has been knowledge and awareness campaigns aiming at inducing changes in behaviour by educating consumers of the scale and impact of food waste, and on the meaning of date labelling. We argue that this approach is insufficient in achieving food waste reduction on a satisfactory scale, and that the potential of implementing measures into the actual contexts of food waste related practices should be further explored and developed. The research presented in this article is based on fieldwork from 26 households in Oslo, Norway. By applying a practice-oriented approach to food waste drivers, we focus on five food waste related practices: acquiring, storing, assessing, valuing and eating. Based on our analysis of how these practices are causing food waste, we identify decisive moments and contexts for food waste prevention and discuss examples of measures that could be further explored. The aim is to inspire a more contextual approach to food waste prevention by policy makers and organisations.

家庭食物垃圾已成为决策者和组织日益关注的问题，因为最近的研究表明，在发达国家，消费者浪费了大约一半的可食用食物。解决该问题最适用的措施是知识和意识运动，旨在通过教育消费者有关食物垃圾的规模和影响以及日期标签的含义，从而引起行为变化。我们认为，这种方法不足以实现令人满意的规模的食物垃圾减少，因此应进一步探索和开发在与食物垃圾有关的实际情况下实施措施的潜力。本文提供的研究基于挪威奥斯陆的26个家庭的田野调查。通过对食品浪费驱动因素采用以实践为导向的方法，我们关注与食物垃圾有关的五种做法：获取，存储，评估，评估和饮食。在我们对这些做法如何造成食物浪费的分析的基础上，我们确定了防止食物浪费的决定性时刻和背景，并讨论了可以进一步探索的措施示例。目的是激发政策制定者和组织采取更切合实际的方法来预防食物浪费。
